Mason was forced to undergo surgery after clashing heads with Gary Cahill at Stamford Bridge in 2017

But Cech, who himself suffered a depressed skull fracture while playing for Chelsea in 2006, believes Mason should be applauded for the way in which he dealt with his rehabilitation.

The Arsenal goalkeeper wrote on Twitter: "Yesterday was a sad day for one incredible young man @RyanMason.

Cahill also took to social media to express his support for Mason, writing on Twitter: "Devastated to hear today's news from Ryan.

Cech has worn a head guard since fracturing his skull in 2006

"Competing for a corner is something we've done thousands of times and to see those consequences for a top professional like Ryan is heartbreaking.

"Sending all my love to him and his family, and wishing him the best for the future."
